[coreboot] ASUS M4A77TD-PRO. No boot, nothing on the serial port. I'm quite lost.

Hm this is strange. Maybe you can try with 9600 ?  I checked your superiotool 
dump and it seems that you dont need to call it8712f_24mhz_in check if you do 
not call it by accident.

I would suggest to try to make it work with serialICE first, then fix the 
coreboot console as second step. Go to www.serialice.com and download it.

It is some kind of simple monitor which can execute various IO operations 
through serial port.

I'm attaching a file which could do the trick for you. Set the baudspeed to 
38400 and select that asrock board in kconfig. Replace the existing file with 
attached, and compile. Not sure if padding is there so if you get 64KB image 
then you need just to place the image in last 64KB of the flash.

Then use minicom or whatever and see if you get the serialice prompt. If so, you 
just need to fix the coreboot to do same thing.

Thanks,
Rudolf
